Module reth::rpc::api::servers::eth::helpers

Behaviour needed to serve eth_ RPC requests, divided into general database reads and specific database access.

Traits with Load prefix, read atomic data from database, e.g. a block or transaction. Any database read done in more than one default Eth trait implementation, is defined in a Load trait.

Traits with Eth prefix, compose specific data needed to serve RPC requests in the eth namespace. They use Load traits as building blocks. EthTransactions also writes data (submits transactions). Based on the eth_ request method semantics, request methods are divided into: EthTransactions, EthBlocks, EthFees, EthState and EthCall. Default implementation of the Eth traits, is done w.r.t. L1.

EthApiServer, is implemented for any type that implements all the Eth traits, e.g. reth_rpc::EthApi.

Modules

• block
  Database access for eth_ block RPC methods. Loads block and receipt data w.r.t. network.
• blocking_task
  Spawns a blocking task. CPU heavy tasks are executed with the rayon library. IO heavy tasks are executed on the tokio runtime.
• call
  Loads a pending block from database. Helper trait for eth_ transaction, call and trace RPC methods.
• error
  Helper traits to wrap generic l1 errors, in network specific error type configured in EthApiTypes.
• fee
  Loads fee history from database. Helper trait for eth_ fee and transaction RPC methods.
• pending_block
  Loads a pending block from database. Helper trait for eth_ block, transaction, call and trace RPC methods.
• receipt
  Loads a receipt from database. Helper trait for eth_ block and transaction RPC methods, that loads receipt data w.r.t. network.
• signer
  An abstraction over ethereum signers.
• spec
  Loads chain metadata.
• state
  Loads a pending block from database. Helper trait for eth_ block, transaction, call and trace RPC methods.
• trace
  Loads a pending block from database. Helper trait for eth_ call and trace RPC methods.
• transaction
  Database access for eth_ transaction RPC methods. Loads transaction and receipt data w.r.t. network.
• types
  Trait for specifying eth API types that may be network dependent.
